Example of how use <optional>-dependency from a dependency used in your
project.
If a dependency in a project has a optional dependency defined,you has to
define the optional dependency as a dependency in your project. But you has
also to set the version for this dependency.
In this example is the optional dependency of javassist/cglib (bytecode
manipulation library) in hibernate-core used, to show how you specify
this dependency without to define the version. The example show how we can
reuse the version defined in the hibernate-parent artifact.
